CodeMirror highlighting on find - codemirror

I want to recreate the find function in CodeMirror for highlight each occurrence like showed in this demo.
I have created an example using marks, but highlight only the first occurrence.

Changing your if (cursor.findNext()) to while (cursor.findNext()) might already get you somewhere. It is more efficient (though also a little more complicated) to use an overlay instead, which is what the built-in search functionality does.

Getting reftex recomendations for labels when creating new sections

In TeX-latex-mode under Emacs (26.1) using the reftex minor mode,
When pressing C-c (, the command reftex-label (found in reftex-mode-map, from reftex-ref.el) gives pretty good suggestions of label according to context for sections (with the default value of reftex-insert-label-flags).
When pressing C-c C-s, the command LaTeX-section (found in LaTeX-mode-map, defined in latex.el) offers to enter a label for the section, with no suggestion (other than a prefix based on the level of the section, which is useful but much less than the one based on the title section offered by reftex-label).
How can one configure LaTeX-section to make the same suggestions as reftex-label for sections?
The hook LaTeX-section-hook along with the variable LaTeX-section-label would seem the right candidate for that purpose, but the documentation states that
Some LaTeX packages (such as fancyref) look at the prefix to
generate some text around cross-references automatically. When using
those packages, you should not change this variable.
for one, I assume that reftex is one of such packages, and second, I was expecting to be able to give a function inside a hook, not a list of prefixes, I wonder if I misunderstood what a hook is?
I think that one would "just" need to get LaTeX-section to abstain from offering a label and to call the function reftex-label immediately after each LaTeX-section call, but if it is not LaTeX-section-hook, I do not know which one it could be?
Before starting programming something which could involve stuff as complicated as refactoring both latex.el and reftex-ref.el, I thought I would ask in case I was missing an easier solution!!!

VS Code Refactoring: Change all occurences - but only in block scope

When using "change all occurences" in VS Code, it will just search the whole file for matches and change them. Is there a similar feature doing the same thing, but limiting it to function or block scope?
Let's take an example where I would need that: I'm having a React file with several components and want to refactor a class component to a functional component, so I'm changing all occurences of this.props to props. However, I obviously don't want to change all the other class components as well that are supposed to stay class components. :-)
This seems like such a standard use case, but I'm not able to find it anywhere in VS Code. If it's not possible (yet, or for some good reasons) is there another way to achieve what I'm trying to do?

Check out the 'Add Selection To Next Find Match' functionality. It allows you to highlight the first occurrence you'd like to change, then using a keyboard shortcut, highlight the next occurrence and so on until you've selected all the instances you want to change. When all to-be-changed occurrences are selected, you can edit the selected text normally. Just remember to hit the escape key a couple times after editing to return to a single cursor!
Here are the keybindings for the command, it's Cmd+d on Mac:
https://code.visualstudio.com/docs/getstarted/keybindings
I find it very useful when renaming variables, there's also a shortcut to skip occurrences (Cmd+k Cmd+d) in case there is text you don't want to change in between.

Rebind keys in Emacs to change commenting style in source code

I am trying to document certain sections of my code using Doxygen. I want to use the javadoc
style of comments viz
/**
* My Documentation goes here
*/
Now in Emacs I can comment out a certain block of text by selecting it and by pressing Meta+;. This comments out the lines by placing a // in front of all the lines selected.
Since most of the time I will be writing comments in my code which will be documented using Doxygen, I want to rebind the Meta+; to give me a javadoc style of comments.
How do I do that?

Use doxymacs. You'll have to rebind keys to your taste, but the bindings it comes with are pretty good.

Code is not documentation. Wouldn't you want to use javadoc style comments only for documentation?
It sounds like you actually want a snippet/skeleton system to insert a java-doc template that you can flesh out. If so I recommend yasnippet.

Better color syntax for CoffeeScript in emacs?

I've seen that when I write a function in coffeescript-textmate it colors the name of function
pleasePutMeSomeColor = () -> console.log "textmate works great!"
in this example pleasePutMeColor is colored inside textmate. This allows me to recognize which are functions much quicker. But when I write the same example inside emacs this word isn't colored. It is harder to identify which are functions.
Is there a way to highlight functions with a different color in emacs?

Are you using defunkt's coffee-mode? That's the only CoffeeScript syntax highlighting plugin for Emacs that I'm aware of; it's under active development, so feel free to submit an issue if you have a specific suggestion.

yup...I'm going to answer my question:
Inside github there is a defunkt coffee-mode fork that adds syntax highlighting for functions.
https://github.com/handle/coffee-mode
It isn't perfect but works well...I hope that it will be added to the official coffe-mode repo.

How do you display code snippets in MS Word preserving format and syntax highlighting?

Does anyone know a way to display code in Microsoft Word documents that preserves coloring and formatting? Preferably, the method would also be unobtrusive and easy to update.
I have tried to include code as regular text which looks awful and gets in the way when editing regular text. I have also tried inserting objects, a WordPad document and Text Box, into the document then putting the code inside those objects. The code looks much better and is easier to avoid while editing the rest of the text. However, these objects can only span one page which makes editing a nightmare when several pages of code need to be added.
Lastly, I know that there are much better editors/formats that have no problem handling this but I am stuck working with MS word.

Here is the best way, for me, to add code inside word:
Go to Insert tab, Text section, click Object button (it's on the right)
Choose OpenDocument Text which will open a new embedded word document
Copy and paste your code from Visual Studio / Eclipse inside this embedded word page
Save and close
Advantages
The result looks very nice. Here are the advantages of this method:
The code keeps its original layout and colors
The code is separated from the rest of the document, as if it was a picture or a chart
Spelling errors won't be highlighted in the code (this is cool !)
And it takes only few seconds.

Download and install Notepad++ and do the following:
Paste your code in the window;
Select the programming language from the language menu;
Select the text to copy;
Right click and select Plugin commands -> Copy Text with Syntax Highlighting;
Paste it into MS Word and you are good to go!
Update 29/06/2013:
Notepad++ has a plugin called "NppExport" (comes pre-installed) that allows you to copy to RTF, HTML and ALL. It permits dozens of languages, whereas the aforementioned IDEs are limited to a handful each (without other plug-ins).
I use Copy all formats to clipboard and "paste as HTML" in MS word.

After reading a lot of related answers, I came across my own solution, which for me is the most suitable one.
Result looks like this:
As you can see, it is the same syntax highlighting like on Stack Overflow which is quite awesome.
Steps to reproduce:
on Stack Overflow
Goto Ask Question (preferably with Chrome)
Paste Code and add a language tag (e.g. Java) to get syntax hightlighting
Copy code from preview
in Word
Insert > Table > 1x1
Paste code (you may need to use Paste Special... > Formatted Text (RTF) from the Edit menu to not lose the syntax hilighting)
Table Design > Borders > No Border
Select code > Edit > Find > Replace
Search Document ^p (Paragraph Mark)
Replace With ^l (Manual Line Break)
(This is required to remove the gaps between some lines)
Select code again > Review > Language > check "Do not check spelling or grammar"
Finally add a caption using References > Insert Caption > New Label > name it "Listing" or sth

There is a nice Online Tool for that : https://www.troye.io/planetb/
Just copy the generated code and paste it into your word editing software. So far I've tried it on MS Word and WPS Writer, works really well.
Doesn't play nice with Firefox but works just fine on Chrome (and IE too, but who wants to use that).
One of the main benefits is that, unlike the Code Format Add-In for Word, it does NOT mess with your code, and respects various languages' syntax.
I tried many other options offered in other answers but I found this one to be the most efficient (quick and really effective).
There is also another online tool quoted in another answer (markup.su) but I find the planetB output more elegant (although less versatile).

Output :

I type my code in Visual Studio, and then copy-paste into word. it preserves the colors.

When I've done this, I've made extensive use of styles. It helps a lot.
What I do is create a paragraph style (perhaps called "Code Example" or something like that) which uses a monospaced font, carefully chosen tabs, a very light grey background, a thin black border above and below (that helps visibility a lot) and with spelling turned off. I also make sure that inter-line and inter-paragraph spacing are set right. I then create additional character styles on top (e.g., "Comment", "String", "Keyword", "Function Name Decl", "Variable Name Decl") which I layer on top; those set the color and whether the text is bold/italic. It's then pretty simple to go through and mark up a pasted example as being code and have it come out looking really good, and this is works well for short snippets. Long chunks of code probably should not normally be in something that's going to go on a dead tree. :-)
An advantage of doing it this way is that it is easy to adapt to whatever code you're doing; you don't have to rely on some IDE to figure out whatever is going on for you. (The main problem? Printed pages typically aren't as wide as editor windows so wrapping will suck...)

Maybe this is overly simple, but have you tried pasting in your code and setting the font on it to Courier New?

Try defining a style called 'code' and make it use a small fixed width font, it should look better then.
Use CTRL+SPACEBAR to reset style.

If you are using Sublime Text, you can copy the code from Sublime to MS Word preserving the syntax highlighting.
Install the package called SublimeHighlight.
In Sublime, using your cursor, select the code you want to copy, right click it, select 'copy as rtf', and paste into MS Word.

I'm using Easy Code Formatter. It's also an Office add-in. It allows you to select the coding style / and has a quick formatting button. Pretty neat.

In case you're like me and are too lazy or in a hurry and don't want to download additional software, you can use http://markup.su/highlighter/. It's very straight forward and supports several highlight themes and many programming languages. In my case I was using Visual Studio Code, which doesn't allow copying with format due to CSS involved in styling (as reported here).
Copy the text from the Preview box and then in Word go to Insert -> Textbox, paste the Preview from the website, highlight all the text, and then disable spell checking for that textbox.
This is what the code looks like finally.

The best way I found is by using the table.
Create a table with 1x1. Then copy the code and paste it.
If you're using the desktop app then it will inherit the code editor theme color and paste it accordingly, else you can change the table style to any color.
UPDATE ------------------
From Word 2021, you can directly paste the code and it will preserve the formatting. No need to create the table.
Thank you #RdC1965 for mentioning this.

This is a bit indirect, but it works very nicely. Get LiveWriter and install this plugin:
http://lvildosola.blogspot.com/2007/02/code-snippet-plugin-for-windows-live.html
Insert your code using the plugin into a blog post. Select all and copy it to Word.
It looks great and can include line numbers. It also spans pages decently.

Vim has a nifty feature that converts code to HTML format preserving syntax highlighting, font style, background color and even line numbers. Run :TOhtml and vim creates a new buffer containing html markup.
Next, open this html file in a web browser and copy/paste whatever it rendered to Word. Vim tips wiki has more information.

In my experience copy-paste from eclipse and Notepad++ works directly with word.
For some reason I had a problem with a file that didn't preserve coloring. I made a new .java file, copy-paste code to that, then copy-paste to word and it worked...
As the other guys said, create a new paragraph style. What I do is use mono-spaced font like courier new, small size close to 8px for fonts, single spaced with no space between paragraphs, make tab stops small (0.5cm,1cm,..,5cm), put a simple line border around the text and disable grammar checks. That way i achieved the line braking of eclipse so I don't have to do anything more.
Hope I helped ;)

This is the simplest approach I follow. Consider I want to paste java code.
I paste the code here so that spaces, tabs and flower brackets are neatly formated http://www.tutorialspoint.com/online_java_formatter.htm
Then I paste the code got from step 1 here so that the colors, fonts are added to the code http://markup.su/highlighter/
Then paste the preview code got from step 2 to the MS word. Finally it will look like this

You can use VS code to keep code format and highlighting. Directly copy and paste code from VS.

you can simply use this Add-in on any office program.
Go to insert tab, then Get Add-ins, and search for Easy Syntax Highlighter
It supports
185 languages and 89 themes.
Automatic language detection.
Multi-language code highlighting.

Use a monospaced font like Lucida Console, which comes with Windows. If you cut/paste from Visual Studio or something that supports syntax highlighting, you can often preserve the colour scheme of the syntax highlighter.

Answer for people trying to resolve this issue in 2019:
Most answers to this question are outdated by now. I wish there was a way to reinspect old questions and answers every now and then!
The method I found for this question that works with Office 365 and its associated programs can be found here.

I'm using Word 2010 and I like copying and paste from a github gist. Just remember to keep source formatting!
I then change the font to DejaVu Sans Mono.
You can opt to copy with or without the numbering.

Copying into Eclipse and paste it in Word is also another option.

You can also use SciTE to paste code if you don't want to install heavy IDEs and then download plugins for all the code you're making. Simply choose your language from the language menu, type your code, high-light code, select Edit->Copy as RTF, paste into Word with formatting (default paste).
SciTE supports the following languages but probably has support for others: Abaqus*, Ada, ANS.1 MIB definition files*, APDL, Assembler (NASM, MASM), Asymptote*, AutoIt*, Avenue*, Batch files (MS-DOS), Baan*, Bash*, BlitzBasic*, Bullant*, C/C++/C#, Clarion, cmake*, conf (Apache), CSound, CSS*, D, diff files*, E-Script*, Eiffel*, Erlang*, Flagship (Clipper / XBase), Flash (ActionScript), Fortran*, Forth*, GAP*, Gettext, Haskell, HTML*, HTML with embedded JavaScript, VBScript, PHP and ASP*, Gui4Cli*, IDL - both MSIDL and XPIDL*, INI, properties* and similar, InnoSetup*, Java*, JavaScript*, LISP*, LOT*, Lout*, Lua*, Make, Matlab*, Metapost*, MMIXAL, MSSQL, nnCron, NSIS*, Objective Caml*, Opal, Octave*, Pascal/Delphi*, Perl, most of it except for some ambiguous cases*, PL/M*, Progress*, PostScript*, POV-Ray*, PowerBasic*, PowerShell*, PureBasic*, Python*, R*, Rebol*, Ruby*, Scheme*, scriptol*, Specman E*, Spice, Smalltalk, SQL and PLSQL, TADS3*, TeX and LaTeX, Tcl/Tk*, VB and VBScript*, Verilog*, VHDL*, XML*, YAML*.

If you are using Intellij IDEA, just copy the code from the IDE and paste it in the word document.

You can host one yourself since it is open source. The code is on github.

There really isn't a clean way to do it, and it could still look fishy based on your exact style settings.
What you could try to do is to first run a code-to-HTML conversion (there are many programs that do that), and then try to open up the HTML file with word, that might hopefully provide you with the formatted and pretty code, and then copy and paste it into your document.

I was also looking for it and ended up creating something for my code display.
Here's a good way:
Create a rectangular form and place your text inside.
Change the font to Consolas and size ~10.
Change the text font to gray near-black (gray 25%, darker 75%)
Use darker colors to highlight your text if needed and choose one to be the contour.

I have created an easier method using tables, as they are easier to create, manage, and more consistent (with the possibility to save the table's style inside the document itself), but I couldn't find a better way for code colouring scheme, sorry for that.
Steps:
Create a 3x3 table.
Select the table, and make its borders invisible ("No Borders" option), and activate "View Gridlines" option.
Make the adjustments to cells' spacing and columns' widths to get the desired aspect. (You will have to get in "Table Properties" for fine tuning).
Create a "Paragraph Style" with the name of "Code" just for your code snippets (as mentioned in https://stackoverflow.com/a/25092977/8533804)
Create another "Paragraph Style" with the name of "Code_numberline" that will be based upon the previous created style, but this you will add a numbering line in its definition (this will automate line numbering).
Apply "Code_numberline" to the first column, and "Code" to the 3 column.
Add a fill in the middle column.
Save that table style and enjoy!

The best presentation for code in documents is in a fixed-width font (as it should appear in an IDE), with either a faint, shaded background or a light border to distinguish the block from other text.

If its Java source code copy it to Visual Studio and then copy it back to Word.
